Conceptual advances within the organic sciences are marked through the applica­ tion of latest suggestions and experimental innovations. Nowhere has this ge­ neric precept been extra obvious than within the learn of testicular cells, as judged via the evolution of issues offered on the Testis Workshop during the last 23 years.

The two types ofinformation therefore eomplement eaeh other and serve also to point out agreement or differenees for elements for which direet 26 I. An Approach to Astrophysics comparisons are available. 3). 1:7 Origin ofthe Solar System Sometime around the era when the Sun formed, the system of planets became established too. Was the Solar System formed after the Sun already was several hundred million years old; or were the Sun and the planets born in one and the same process? Did the Solar System form out of a single cloud of matter surrounding the Sun; or was there another star involved in the birth of the planets?

Units on the abscissa are multiples of the radius of each galaxy's optical disko Data points refer to radio observations of hydrogen gas velocities (in km S-I). While the data points show a fiattened curve out to large distances from the galaxy's center, we would expect a slow drop in rotational velocity if mass in these galaxies were concentrated as centrally as the light-emitting stars (Ma97).

4. As a star moves off the main sequence it apparently gets redder and, if anything, more luminous than it was on the main sequence. At lower temperatures, however, an object always emits less radiation per unit area. Correspondingly, the only way that this particular course of evolution can proceed is for the star to grow as it moves offthe main sequence. The stars become giants. Their radi i increase by factors of 10 to 100. Let us see how such stages evolve. For this purpose the study of globular clusters is most instructive.
